I worked for Mozilla over a period during which we went to having no telemetry to good telemetry and the benefits for quality were huge, especially for crashes. Without crash telemetry you simply have to guess which bugs are the most important to fix first. With telemetry you know. This is especially important when a bug suddenly shows up in the field, e.g. some antivirus vendor ships an update that breaks your product. Diverse teams are good but you are never going to have a team that truly represents the experiences of non-technical people.
